Chapter Sixteen: Teach Me Something New

Lisa shook her head and sighed as she watched Allison putting away her laundry. "Your underwear is so boring." She lamented, making Allison look up from what she was doing and look at the older woman.

"Huh?" Allison looked in her underwear drawer. Now that Lisa mentioned it... Damn, it was boring.

"I mean... You have some color, but, honey, it's all the same cut." Lisa clucked her tongue.

"So, first you get Greg to buy condoms, and now you're trying to convince me to buy lingerie?" Allison shook her head and threw more clothes in the drawer. "And you wonder why we started having sex in your house."

Cuddy shivered at that; she really didn't want it confirmed so blatantly. "Come on, you know you want to wear something sexy for him." She nudged the younger woman's shoulder.

"Greg said that I don't need to try. He said I look hot like this." Allison gestured to her jean and form fitting tee.

Shaking her head in disappointment, Lisa tried to convince further, "Yeah, but feeling sexy can completely change the outcome of the night."

Intrigued, Allison looked at her newest friend, "How so?" Her eyes narrowed with curiosity.

Lisa went to sit on Allison's bed but stopped herself. She couldn't sit on that bed, knowing that Allison and House had... She shuddered. "Well, House may like how you look dressed like that." She gestured to Allison's clothes, "But, do you feel sexy wearing a t-shirt and jeans?" Allison fidgeted a little, realizing that she really didn't. "But if you were wearing something sexy underneath? Then you could get your confidence up, and still be wearing the clothes he likes to see you in." She winked.

Allison blushed slightly. She looked at her reflection in the mirror. Her hair was pulled back in a sloppy ponytail, her fitted, green t-shirt with TMNT stamped on it and her scuffed Skechers that were half hidden by the torn up hem of her blue jeans. Allison could visualize her plain white bra and the black bikini cut panties underneath and she didn't feel sexy at all.

"There's nothing wrong with wanting to feel hot." Lisa pointed out. "Do you want to go shopping?" She smirked as she watched Allison look at herself in the mirror. Allison looked at Lisa with the reflection of the mirror. The look on her face was mischievous and Lisa knew that she might have finally gotten herself in way too deep.

---------------------------

As the two women perused the boutique's wares, flipping through articles of clothing and matching sets of bras and panties, Allison began to wonder what to talk about. Biting her lip nervously, she finally got up the guts to ask Lisa something she'd been curious about.

"Lisa," Allison began to blush before she could even ask, "can I ask you something?"

Cuddy stopped flipping through the clothes to look at the younger woman, "What's up?"

"Okay, this is going to sound really stupid, but," her voice dropped very low, "I've been really sore the mornings after Greg and I have sex." She whispered.

Lisa seemed to be thrown for a loop with that statement, but quickly recovered, putting on her "doctor face". "Well, Ally, you're still new to the whole thing."

"It's not just that... I mean," her face turned beet red, "some of the positions I try just really hurt and I feel so stupid when he stops me and tells me how to move my body so it doesn't hurt. I feel like I'm his fucking patient!" She moaned. "And when I finally do get it all figured out, I can't even do it for very long before my muscles start shaking."

"Apparently you have... Lot's of questions." Lisa sighed. "Come on, let's get some coffee and we'll come back to this. You can't shop for sexy things when you're so self conscious." She lead the younger woman to the food court of the mall and they got some coffee and sat down. "First of all, Ally, you've gotta remember, he's been having sex a lot longer than you. It sounds weird, but his body is used to that type of muscle use. Not to mention, he's probably not using half the muscles you are when you take the lead." Allison flushed a bit but nodded, "And in all consideration, I think you should be glad that he cares so much for you that he takes the time to slow you down and help you figure it out." Allison nodded again, guiltily. "As for hurting in the morning, maybe you're going too fast?"

"But... I like it when he goes fast." Allison mumbled, making Lisa laugh.

"Yeah, but maybe you should try going a little slower for a while." The older woman suggested, "Just until your body starts adjusting to him. After all, you've only been having sex for four weeks out of your 21 years, and it's not like it's been every day. It pales quite a bit in comparison." Lisa sighed at Allison's disheartened look, "Just stop being so hard on yourself, believe me, House is not going to get annoyed with you just because you can't keep up with him. And considering how much of a control freak he is, I seriously doubt he minds keeping the lead for the time being."

"But when I got on top of him-"

Lisa clamped her hands over her ears, "LAlalalaalalalala! I don't CARE that I'm a doctor!" She yelled, "I can't HEAR YOU! Lalalalalalala! I am not going to listen to you talk about mounting my friend! Lalalaalalalala!"

Allison laughed and drank her coffee as Lisa calmed down and grabbed her own cup.

After their talk, Allison found it easier to shop for lingerie that she knew would drive her boyfriend crazy. However, when her bill was rung up, Allison felt like she'd pass out. She had just spent nearly her entire summer's worth of spending money on underwear. Shaking her head, she couldn't believe it, but thinking of the drooling look that would appear on House's face, she quickly got over it.

----------------------------------

Upon arriving back at Cuddy's house, Allison immediately went to work washing her new accessories after liberating them from their tags and hangers. She groaned that most needed to be hand washed, and hoped that they would be dry by the time House came to pick her up that evening.

Lisa watched the younger woman's frantic cleaning and just laughed.

Luckily, most of the thin fabric materials dried, and Allison went to work changing and getting ready for her evening with her boyfriend. It was strange, but when she looked in the mirror and saw her body clad in its usual t-shirt and jeans, she actually did feel sexier knowing that something lacy and flattering was beneath it. When the doorbell rang, Allison slid her feet in a pair of flip flops and hopped down the stairs.

When she came to the bottom of the stairs, Lisa was already opening the door and letting House inside. With a slight skip, Allison jumped into his arms, her legs automatically curling around his hips as his arms encircled her waist.

"Please tell me you didn't give her caffeine." House groaned at Cuddy.

"Just some coffee." Lisa shrugged.

"Great, you have doomed me for the evening." He muttered around the side of Allison head as she buried her face in the crook of his shoulder. "She will be utterly insatiable with caffeine in her."

"Yes, my evil plan worked!" Lisa threw her arms up in a mockery of sinister intent.

House groaned and turned back towards the door, "Ally, it might be a little obvious to the neighbors if I walk out the door with you wrapped around me."

"Yes, and her getting out of your car limping and hunched over is no indicator of rough sex." Lisa rolled her eyes, "I doubt my neighbors have any clue who you are, House."

Rolling his own eyes, House flung the front door open and walked out, Allison still secured around his middle.

When they came to House's condo, Allison got out of the car and followed House to the door where she waited impatiently for him to unlock it. "I had an idea!" She said, closing the door behind her.

"Which is?"

"You're going to help me study!" Allison grinned, making House flop onto the couch in exhaustion.

"What subject?" He moaned, not in the mood for anything work related.

"Anatomy." She jumped over the back of the couch, nearly landing on him, but instead catching herself and straddling his waist.

"That could be fun." He grinned, running his hands up her sides, but she quickly lept off of him and sat on the sturdy coffee table. His grin quickly faded.

"I'm serious." She pouted, "I need help with the origins, insertions and actions of muscles."

Groaning, House went limp on the couch. "Where to start."

"Upper extremities."

"Fine." House rubbed his eyes and sat up straight, "Name the four rotator cuff muscles."

"Supraspinatus, infraspinatus, teres minor, subscapularis." She rattled off.

"Their origins?"

"Supraspinus fossa, infraspinus fossa, lateral border of the scapula, subscapular fossa." Allison said, trying to concentrate.

"Insertions."

"Greater tubricle, greater, greater, lesser."

"And action."

"Adducts-"

"Supra abducts." House stopped her, surprised that she'd missed that considering how well she knew the rest. He saw her kick off one of her flip flops.

"Okay, abducts, adducts, adducts-"

"Don't forget that infra and teres also externally rotate the humerus." He pointed out, and he saw her slide off her other flip flop.

"And subscapularis internally rotates." She finished.

House stared at her for a moment and shook his head, "Latissimus dorsi. Same order."

Allison thought for a moment, "Thoracolumbar aponeurosis is the origin. Insertion is the bicipital groove. And action," House watched in amusement as Allison started moving her arm in strange ways, "extension," she said as she pulled her arm backwards, "and adduction."

"And medial rotation." House added. This time, Allison slipped off her jacket, and House's brow scrunched together, "Wait a minute... Are we playing strip studying!?" He gawked.

"I was wondering how many of these easy questions I was going to have to miss before you caught onto that!" Allison laughed, tossing her jacket at him.

"Well, I'm going to have to be a little harder then, aren't I?" He grinned, leaning forward and squaring his shoulder for the ultimate battle over muscle knowledge.

Needless to say, House ended up skipping the larger muscles and started going to the complicated ones. Of course, he also knew that she was at a great disadvantage with clothes she could take off, for she wore only her usual t-shirt and jeans now. Wanting to end the game quickly, he blurted out palmaris longus, which baffled Allison effectively, and she quickly lost her belt, pants and shirt, for she didn't know the origin, insertion or action. Though she was disappointed that he'd put an abrupt halt to her fun and games, Allison was excited to be removing her clothes to show him the items she'd purchased that day.

Undoing her belt, Allison took hold of the buckle and gave it a hard yank, whipping it from the loops that had secured it, tossing it to the side. House leaned back into the couch and watched her as she unbuttoned her pants and slid the zipper down before tugging up the tail of her shirt and pulling the snug fitting tee from her body. House repressed a moan as Allison's fingers trailed over the smooth expanse of her torso, revealing every gorgeous inch of flesh as she tugged and removed her clothes. As she flung the t-shirt across the room, House licked his dry lips when he saw her deep crimson shaded bra, which was lacy and nearly transparent. Shirtless, Allison pushed the waist of her pants down slowly, accenting the beautiful curves up her hips before an identical deep red lace appeared beneath the denim. House groaned and stood up as she stepped out of her pants. Grabbing her about the waist, he pressed his mouth against hers with a hungry growl.

At the sound he made against her mouth, Allison could feel a familiar excited shiver pulse downward and spread heat throughout her body. Her hands went to the tail of his shirt and pulled it upwards, only breaking the fusion of their mouths long enough to tug it over his head and toss it aside. His hands went to her breasts caressing and squeezing them as as she pushed him backwards until the backs of his legs hit the couch and he was forced to sit. Crawling into his lap, Allison quickly shimmied as close as she could to him. His hands ran up the sides of her body, pushing her back so that her hands went to his knees and he could trace his moist tongue from just above her navel to where her bra cut him off. Pulling her back to his lips, he kissed her as she rolled her hips against the growing erection that was concealed by his pants. Feeling the friction drove him mad as his hands roamed and caressed, scratched and tickled her flesh. Finally she pulled away and looked at him with something between shyness and heated passion. An odd combination, but oh so invigorating.

Sliding off of his lap, Allison undid his fly and gave his pants a hard tug, to which he raised his hips and let her drag the clothes from his body. Curling up alongside him on the couch, once the chore of removing his pants and boxers had been accomplished, Allison laid down on her stomach, head resting on his thigh.

Looking down at her, House placed his hand on her head, stroking her hair lovingly. He wasn't yet sure what her intentions were, but seeing her face so close to his cock had him feeling more and more aroused.

Sliding her hand along the inside of his thigh, Allison took her opportunity to observe his body entirely. She could see his member twitch with every caress of her fingertips on his inner thigh, and the way that the muscles beneath her hand flexed and shook in curious anticipation. Looking up at him, feigned innocence on her face, Allison took his shaft in his hand and reveled in the shudder she saw pass through his body when she gripped him as firmly as she dared. Propping herself on her knees and her free hand, Allison stroked him and watched the subtle reactions his body made. Little spasms of muscles in his legs that were repressed thrusts of his hips, and twitches in his length that she held in his hands, and yet the whole time all he did was watch her face. He watched the way she watched him, how she tried to memorize his every reaction and discover what gave him the most pleasure.

When the little drops of pre-cum oozed from the tip of his member, House moaned when she dipped her mouth down to taste him without a second thought. She didn't pull away when she enveloped his head between her lips, instead, she remained to suckle and encourage more of his excretions. Finally tearing his eyes from her administrations, House clamped his eyelids shut, his head tilting against the back of the couch. Hand trailing down down the length of her back, House ran his palm over the lacy red panties, giving the swell of a tender cheek an encouraging squeeze.

Allison moaned with his cock between her lips, and House shut his eyes tighter at the vibrations that little pleasurable sound sent through him. Sliding his fingers towards the center of her ass, he slowly stroked her through her panties, feeling the moisture already saturating them and causing his fingers to become slick. Allison rolled her hips against his fingers, taking him deeper into her mouth, as if to tell him to keep up what he was doing, and that she would reward him.

Licking his dry lips, House pressed his middle finger harder against the fabric barrier against her entrance before dipping lower to rub the material against her clit which he knew was probably already swollen and awaiting his touch. When she whimpered and pulled back for air, House quickly removed his hand and pushed her away. He didn't want to waste their first part of the night when he knew that he wanted to be inside of her tight pussy already.

Mewling gently, Allison ran her hands over her body when he pushed her aside. She ached for him, and could feel her nether regions pulsing to welcome him inside of her body. Unhooking the clasp of her bra, Allison flung it aside before she flattened herself onto her back and looked up at him impatiently as he scrambled around for a condom. She decided then that alternative methods of birth control must be sought, for she was becoming increasingly annoyed with stopping to let him put on a rubber.

When House had managed to locate and apply the birth control, Allison was ready and waiting for him, writhing and whimpering on his couch. Swiftly he removed her panties, and Allison turned over onto her stomach, crawling to rest her forearms onto the arms of the couch. House growled deep in his throat as she offered to let him take her from behind despite the discomfort she'd had the morning after they had used this position the first time. However, House wasted no time coming up behind her and pressing the tip of his erection against her slick opening. Sliding the head against her before pressing in, House groaned as she whimpered, feeling the welcomed tightness and spasms of her pussy surrounding him.

"Fuck, Ally, you're so tight." He moaned, sliding his hands on either side of her ass before latching onto her hips and surging forward. Allison moaned and began to hug the arm of the sofa as he bucked and thrust against her. The position made his length drag against some hidden spot within her entrance, causing shudders to tingle down her spine.

"Greg... oh... God... You feel so good like this." She clenched her eyes shut, burying her face against the cushioned arm. Her hips circled and pushed back against his. Pushing as deep as he could, House paused before slowly withdrawing and dragging out an extended moan from Allison's lips that muffled into the sofa. When one of his hands released her hip to wrap around her waist and play with her swollen nub, Allison cried out sharply, quickly tumbling over the edge.

Pounding against her from behind, House could feel her inner walls flutter around him, never ceasing, as cry after cry tore from her throat. He knew she was having a multiple, and it drove him over the edge with her. Even as he came down from his climax, he could still feel her pussy clenching and unclenching around him as he pulled back, dragging her with him to fall onto his chest on the couch.

"I should help you study more often." House murmured against her ear and making her laugh softly.

"Mm," Allison nuzzled against his chest, her leg sliding up and down the length of his own, "I think you could teach me a lot of things." She agreed.

"We'll see." He curled his arms tightly around her, pressing his nose against her hair and breathing in her scent, "But first, I need to learn to control myself around you. If I don't drop by the clinic some time soon and make a guest appearance, people will start to wonder why I'm not interested in my own protege."

"Well, then drop by the clinic, say something snide, and leave," Allison smirked, "it shouldn't be that hard."

"Oh but it is." House murmured, "It's always hard when I see you." Allison flushed, understanding what he meant, "I look at you and everyone knows what I'm thinking. Cuddy and Wilson knew whenever I talked to you, or got an e-mail from you, just because of my mood. Even Stacey knew something was going on." He let his hands run down her sides, "And now that I've been with you... Felt you... Tasted you... I can't see your face or hear your voice without getting hard." His hand ran down the swell of her buttocks and pulled her tightly against his body.

"Keep talking like that," Allison whispered, "and I won't be able to give you enough time to recover from our last go."

"I think I could fuck you again in a matter of minutes." He sat up a bit and Allison followed his movement, she could already feel him beginning to stiffen. Wrapping her arms around him, Allison ground herself on him, "You're going to fuck me to death, aren't you?"

Allison shook her head, "No, I'm going to love you to death."
